Abstract

695,087. Shaft seals. FOOD MACHINERY & CHEMICAL CORPORATION, Jan. 15, 1952 [July 30,1951], No. 1119/52. Class 122(v) In a rotary shaft seal in which a pair of rings 13, 14 surrounding the shaft 9 and each carried in a supporting cup 16, 17 are urged axially into mutual sealing engagement the rings are an easy fit in their supporting cups and to prevent relative rotation therebetween co-operating means are provided on each ring and its supporting cup. Slots 18 in the outer peripheries of the rings 13, 14 are engaged by projections 19 on the supporting cups 16, 17 which have further projections 20 respectively engaging slots 23 and 27 respectively in a disc 6 attached to the shaft housing 8 and in a barrel 26 mounted on a sleeve 12 in an axially slidable but angularly fixed manner by means of pins 28 projecting into axial slots 29 in the outer surface of the sleeve 12. The faces 13a, 14a of the rings 13, 14 are urged into contact by a spring 33 compressed between a flange 34 on .the sleeve 12 and a ring 32 acting on packing 31 forming a seal between the barrel 26 and the sleeve 12 which is axially movable on the shaft 9 to vary the compression of the spring 33. The sleeve 12 is held in the desired position on the shaft by set bolts 37, which deform it into frictional contact with the shaft. Preferably the rings 13, 14 are of a cemented tungsten or boron carbide and the supporting cups 16, 17 of a semi resilient material, such as tetrafluoro-ethylene.
